Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a clamping and pressing tool. Background Technology

[0002] During ultrasonic welding, high-frequency vibration can cause resonance in the welded terminals, leading to defects such as cracks and detachment of internal spring sheets. A related technology provides a crack-preventing clamping and pressing fixture that uses a crack-preventing push plate to clamp the welded terminals with a certain force during welding, limiting and altering the vibration frequency of the terminals to achieve crack prevention. However, this crack-preventing clamping and pressing fixture has the following drawback: during the transmission of vibration from the welding position to the clamping position, the portion between the welding position and the clamping position is prone to cracking after receiving the welding vibration.

[0003] Therefore, there is an urgent need for a clamping and pressing tool to solve the above-mentioned technical problems. Utility Model Content

The two pressing mechanisms are respectively positioned on both sides of the terminal to be welded to clamp both sides of the terminal. The lifting mechanisms are connected to the pressing mechanisms to drive the pressing mechanisms to rise and fall. The pressing mechanisms and lifting mechanisms are arranged in a one-to-one correspondence. The pressing mechanism includes a push block assembly and a push plate assembly. The push block assembly includes a push block, a first adjusting member, and a first driving member. The push block and the first driving member are connected through the first adjusting member. The push block is used to press the part of the terminal to be welded. During the welding process, the terminal cannot vibrate with the welding head due to the pressure of the push block, thus reducing the number of vibrations and the vibration frequency of the terminal, and avoiding cracking at the welded position. The push plate assembly includes a push plate, a second adjusting member, and a second driving member. The push plate and the second driving member are connected through the second adjusting member. The push plate is used to clamp the terminal to be welded to clamp both sides of the terminal. The first driving member and the second driving member are arranged opposite each other, which saves space compared to arranging the first driving member and the second driving member side by side.

[0024] The downward pressure applied by the push block to the terminal acts directly on the welding area, effectively reducing additional vibrations generated during terminal welding and preventing terminal cracking. Applying downward pressure in the area closest to the welding point is more effective than altering the vibration frequency through clamping in non-welding areas; the Z-axis downward pressure acts directly on the welding surface, directly reducing unwanted additional vibrations and lowering the vibration frequency. Terminals whose vibration frequency cannot be effectively limited by push plate clamping can be restricted by using the push block to press down on the terminal in conjunction with the push plate clamping, thus preventing terminal cracking.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0051] An embodiment of this utility model provides a clamping and pressing fixture for pressing the terminal to be welded, which can press the welding part of the terminal to be welded to avoid vibration generated during terminal welding, thereby preventing cracking.

[0052] Example 1

[0053] like Figures 1 to 4 As shown, the clamping and pressing fixture includes two opposing pressing mechanisms 1 and a lifting mechanism 2. The two pressing mechanisms 1 are respectively disposed on both sides of the terminal 100 to be welded to press the terminal 100 to be welded. The lifting mechanism 2 is connected to the pressing mechanism 1 to drive the pressing mechanism 1 to rise and fall. The pressing mechanism 1 includes a push block assembly 11 and a push plate assembly 12. The push block assembly 11 includes a push block 111, a first adjusting member and a first driving member 112. The push block 111 and the first driving member 112 are connected through the first adjusting member. The push block 111 is used to press the edge of the terminal 100 to be welded, during the welding process. During the welding process, the vibration frequency of terminal 100 is changed due to the pressure of push block 111, which avoids cracking of terminal 100 from the welding area to the clamping area; push plate assembly 12 includes push plate 121, second adjusting member and second driving member 122. Push plate 121 and second driving member 122 are connected through second adjusting member. Push plate 121 is used to clamp terminal 100 to be welded, thereby clamping both sides of terminal 100; first driving member 112 and second driving member 122 are arranged opposite to each other, which saves space compared to first driving member 112 and second driving member 122 being arranged side by side.

[0054] The downward pressure applied by the pusher block 111 to the terminal 100 acts directly on the welding area, effectively reducing the additional vibration generated during welding and preventing cracking. Applying downward pressure in the area closest to the welding point, compared to altering the vibration frequency through clamping in non-welding areas, is more effective because the Z-axis downward pressure acts directly on the welding surface, thus changing the vibration frequency. Therefore, terminals 100 whose vibration frequency cannot be effectively limited by the pusher plate 121 can have their vibration frequency limited by the pusher block 111 pressing down on the terminal 100 in conjunction with the pusher plate 121, preventing cracking.

[0055] In some embodiments, as Figure 3 and Figure 4 As shown, the first adjusting member includes a first wedge block 113, which has a first inclined working surface. A push block 111 is connected to a second wedge block 114, which has a second inclined working surface. The first inclined working surface and the second inclined working surface are in contact. A first driving member 112 is fixedly connected to the first wedge block 113 to drive the first wedge block 113 to press against or move away from the push block 111. When the first driving member 112 pushes the first wedge block 113 forward, the first wedge block 113 has a first inclined working surface. The second wedge block 114 has a second inclined working surface. The first inclined working surface will press against the second inclined working surface. The second wedge block 114 connected to the push block 111 moves towards the terminal 100 under the pressure of the first wedge block 113, and thus tends to clamp the edge of the terminal 100 to be welded. Since the lifting mechanism 2 can drive the pressing mechanism 1 to rise and fall, the lifting mechanism 2 first raises the pressing mechanism 1, and then lowers it after the push block 111 is pushed out, so that the push block 111 presses the edge of the terminal 100 to be welded.

[0056] In some embodiments, continue to refer to Figure 3 and Figure 4 The second adjusting member includes a third wedge block 123, which has a third inclined working surface. A fourth wedge block 124 is connected to a push plate 121, which has a fourth inclined working surface. The third inclined working surface and the fourth inclined working surface are in contact. A second driving member 122 is fixedly connected to the third wedge block 123 to drive the third wedge block 123 to press against or move away from the fourth wedge block 124 connected to the push plate 121. Under the drive of the second driving member 122, the third wedge block 123 moves forward along the axial direction of the second driving member 122. Since the third inclined working surface and the fourth inclined working surface are in contact with each other, when the third inclined working surface moves relative to the fourth inclined working surface, it will force the fourth wedge block 124 with the fourth inclined working surface to move. In turn, the fourth wedge block 124 drives the push plate 121 to move, thereby clamping the terminal from both sides of the terminal 100.

[0057] When the first wedge block 113 extends back under the drive of the first driving member 112, the pushing force on the push block 111 also disappears accordingly. In order to keep the push block 111 in contact with the first wedge block 113 so as to press the terminal 100 again, in some embodiments, the pressing mechanism 1 further includes a limiting frame 14, and the first adjusting member further includes a first elastic member 116. One end of the first elastic member 116 extends into the second wedge block 114, and the other end abuts against the limiting frame 14. In this way, when the push block 111 is squeezed, the first elastic member 116 is compressed. After the pushing force on the push block 111 disappears, the first elastic member 116 will push the push block 111 towards the first wedge block 113 under its own restoring force, so that the first wedge block 113 and the push block 111 remain in contact so as to press the terminal 100 again.

[0058] The third wedge block 123 extends back under the drive of the second drive member 122, and the pushing force on the push plate 121 also disappears accordingly. In order to keep the push plate 121 in contact with the third wedge block 123, in some embodiments, the second adjustment member also includes a second elastic member 126. One end of the second elastic member 126 extends into the fourth wedge block 124, and the other end abuts against the limiting frame 14. The push plate 121 and the push block 111 are both set in the area enclosed by the limiting frame 14. In this way, when the push plate 121 is squeezed, the second elastic member 126 is compressed. After the pushing force on the push plate 121 disappears, the second elastic member 126 will push the push plate 121 towards the third wedge block 123 under its own restoring force, thereby keeping the third wedge block 123 in contact with the push plate 121, so as to facilitate the next clamping of the terminal 100.

[0059] In some embodiments, as Figure 1 , Figure 2 and Figure 5 As shown, the lifting mechanism 2 includes a frame 21, a connecting plate 22, a mounting plate 23, a third drive component 24, and a guide structure 25. The mounting plate 23 is used to install the pressing mechanism 1. The guide structure 25 includes a slide rail and a slider 28. The two ends of the connecting plate 22 are respectively connected to the third drive component 24 and the mounting plate 23. The side wall of the connecting plate 22 is fixedly connected to the slider 28. The frame 21 fixes the slide rail, and the slider 28 is slidably connected to the slide rail.

[0060] like Figure 5As shown, the clamping and pressing fixture also includes a support platform 3 for supporting the terminal 100. The support platform 3 is fixed on the frame 21. Under the action of the lifting mechanism 2, the pressing mechanism 1 can rise and fall relative to the support platform 3, so that the push block 111 and the push plate 121 can move relative to the support platform 3. Specifically, the support platform 3 includes a fourth driving member 32 and a support unit 31. The fourth driving member 32 is fixed on the frame 21, and the support unit 31 is fixedly connected to the fourth driving member 32. The length extension direction of the support unit 31 is perpendicular to the axial direction of the fourth driving member 32. Thus, under the action of the fourth driving member 32, the support unit 31 can rise and fall relative to the mounting plate 23 to meet the placement requirements of the terminal 100. Terminal 100 is disposed in the groove of the bearing unit 31. The arrangement of the groove affects the clamping of terminal 100. When welding, the position of terminal 100 to be welded protrudes from the bearing unit 31 and is located on the lower welding head to be supported by the lower welding head. After the fourth driving member 32 drives the bearing unit 31 to separate from terminal 100, the two oppositely arranged side walls of terminal 100 are exposed. At this time, the two side walls of terminal 100 can be clamped by the push plate 121.

[0061] In some embodiments, combined with Figure 1 and Figure 5 As shown, the lifting mechanism 2 also includes a limiting component for limiting the rising height of the third driving component 24. For example, the limiting component includes a first limiting bolt 41 and a second limiting bolt 42. An upper limiting block 43 is provided on the frame 21, and a C-shaped interference block 45 is provided on the mounting plate 23. One end of the interference block 45 is fixedly connected to the mounting plate 23, and the other end can approach or move away from the upper limiting block 43. The other end is connected to the first limiting bolt 41. After the first limiting bolt 41 contacts the upper limiting block 43, it has a certain buffering effect to avoid a hard collision between the interference block 45 and the upper limiting block 43. A lower limiting block 44 is provided on the frame 21, and a second limiting bolt 42 is provided on the mounting plate 23. The lower limiting block 44 is stationary relative to the second limiting bolt 42, which can limit the downward movement of the second limiting bolt 42.

[0062] The lifting mechanism 2 pushes the pressing mechanism 1 to be in the normal rising state. After the terminal 100 is placed, the push blocks 111 of the pressing mechanisms 1 on both sides move to the welding width dimension, the lifting mechanism 2 lowers the push blocks 111 of the pressing mechanism 1 to press down the terminal 100, and the push plate 121 clamps the terminal 100 and then the welding begins.

[0063] Example 2

[0064] like Figures 5 to 8As shown, the clamping and pressing fixture includes two opposing pressing mechanisms 1 and two lifting mechanisms 2. The two pressing mechanisms 1 are respectively disposed on both sides of the terminal 100 to be welded to press the two sides of the terminal 100 to be welded. The lifting mechanisms 2 are connected to the pressing mechanisms 1 to drive the pressing mechanisms 1 to rise and fall. The pressing mechanisms 1 and the lifting mechanisms 2 are arranged in a one-to-one correspondence. The pressing mechanism 1 includes a push block assembly 11 and a push plate assembly 12. The push block assembly 11 includes a push block 111, a first adjusting member and a first driving member 112. The push block 111 and the first driving member 112 are connected through the first adjusting member. The push block 111 is used to press the terminal 100 to be welded. During the welding process, the vibration frequency of the terminal 100 is changed due to the pressure of the push block 111 at the edge of the area to be welded, thus preventing cracking of the terminal 100 from the welding area to the clamping area. The push plate assembly 12 includes a push plate 121, a second adjusting member, and a second driving member 122. The push plate 121 and the second driving member 122 are connected through the second adjusting member. The push plate 121 is used to clamp the terminal 100 to be welded, thereby clamping both sides of the terminal 100. The first driving member 112 and the second driving member 122 are arranged opposite to each other, which saves space compared to the first driving member 112 and the second driving member 122 being arranged side by side.

[0065] The downward pressure applied by the pusher block 111 to the terminal 100 acts directly on the welding area, effectively reducing the additional vibration generated during welding and preventing cracking. Applying downward pressure in the area closest to the welding point, compared to altering the vibration frequency through clamping in non-welding areas, is more effective because the Z-axis downward pressure acts directly on the welding surface, thus changing the vibration frequency. Therefore, terminals 100 whose vibration frequency cannot be effectively limited by the pusher plate 121 can have their vibration frequency limited by the pusher block 111 pressing down on the terminal 100 in conjunction with the pusher plate 121, preventing cracking.

[0066] The lifting mechanism 2 pushes the pressing mechanism 1 to be in the normal rising state. After the welding terminal 100 is placed, the push blocks 111 of the pressing mechanisms 1 on both sides move to the welding width dimension, the lifting mechanism 2 falls back, the push blocks 111 of the pressing mechanism 1 press down the terminal 100, and the push plate 121 clamps the terminal 100 and the welding begins.

[0067] In some embodiments, as Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, the first adjusting member includes a first driving block 118 and a first positioning post 115. The clamping and pressing tool also includes a limiting body 13. The first driving block has a first inclined groove 1181. One end of the first positioning post 115 extends into the first inclined groove 1181 and can move relative to the first inclined groove 1181. The other end of the first positioning post 115 is fixedly connected to the push block 111. The limiting body 13 is provided with a first limiting groove 131. The first positioning post 115 passes through the first limiting groove 131. The extension direction of the first limiting groove 131 is in the same direction as the movement direction of the push block 111. The extension direction of the first inclined groove 1181 is set at an angle to the extension direction of the first limiting groove 131. The extension direction of the first limiting groove 131 is perpendicular to the axial direction of the first driving member 112. In this way, the first adjusting member can convert the axial movement of the first driving member 112 into the movement of the push block 111 perpendicular to the axial direction of the first driving member 112, thereby bringing the two oppositely arranged push blocks 111 closer to each other. The first drive block 118 has a first inclined groove 1181. One end of the first positioning post 115 extends into the first inclined groove 1181, and the other end of the first positioning post 115 passes through the first limiting groove 131 and is fixedly connected to the push block 111. Since the setting of the first limiting groove 131 can prevent the first positioning post 115 from moving along the length direction of the first inclined groove 1181, the push block 111 can move linearly under the combined action of the first inclined groove 1181 and the first limiting groove 131 to approach or move away from the terminal 100 to be welded.

[0068] In some embodiments, reference Figure 10 The first drive block 118 is also provided with a mounting groove 1182, wherein the mounting groove 1182 is a T-shaped groove, the first drive component 112 is a cylinder, and the cylinder rod of the cylinder is connected to the first drive block 118 through a connecting pin 117. The connecting pin 117 is a T-shaped structure, so that the connecting pin 117 can pass through the mounting groove 1182 to connect the first drive component 112 to the first drive block 118.

[0069] In some embodiments, as Figure 9 , Figure 11 and Figure 12As shown, the second adjusting member includes a second driving block 127 and a second positioning post 125. The second driving block 127 has a second inclined groove 1271. One end of the second positioning post 125 extends into the second inclined groove 1271 and can move relative to the second inclined groove 1271. The other end of the second positioning post 125 is fixedly connected to the push plate 121. The limiting body 13 is provided with a second limiting groove 132. The second positioning post 125 passes through the second limiting groove 132. The extending direction of the second limiting groove 132 is in the same direction as the moving direction of the push plate 121. The extending direction of the second inclined groove 1271 is set at an angle to the extending direction of the second limiting groove 132, and the extending direction of the second limiting groove 132 is set perpendicular to the axial direction of the second driving member 122. In this way, the second adjusting member can convert the axial movement of the second driving member 122 into the movement of the push plate 121 perpendicular to the axial direction of the second driving member 122, thereby bringing the two opposing push plates 121 closer to each other. The second drive block 127 has a second inclined groove 1271. One end of the second positioning post 125 extends into the second inclined groove 1271, and the other end of the second positioning post 125 passes through the second limiting groove 132 and is fixedly connected to the push plate 121. Since the setting of the second limiting groove 132 can prevent the second positioning post 125 from moving along the length direction of the second inclined groove 1271, the push plate 121 can move linearly under the combined action of the second inclined groove 1271 and the second limiting groove 132 to approach or move away from the terminal 100 to be welded.

[0070] In some embodiments, the limiting body 13 is a sheet metal structure, specifically disposed at the top or bottom of the first adjusting member and the second adjusting member, and the limiting body 13 is fixed relative to the first driving member 112 and the second driving member 122. In other embodiments, reference continues... Figure 14 The limiting body 13 has a receiving cavity 133 for accommodating the first driving block 118 and the second driving block 127. The receiving cavity 133 is open at both ends, and the length extension direction of the receiving cavity 133 is in the same direction as the length extension direction of the limiting body 13. This facilitates the connection of the first driving member 112 and the second driving member 122 to the first driving block 118 and the second driving block 127, respectively. It also facilitates the installation of the first driving block 118 and the second driving block 127 into the limiting body 13. The receiving cavity 133 is connected to the first limiting groove 131 and the second limiting groove 132, respectively, so that the first positioning post 115 and the second positioning post 125 can extend out of the receiving cavity 133. In addition, the first limiting groove 131 and the second limiting groove 132 are arranged in parallel, which can avoid positional interference between the push block 111 and the push plate 121 when they move, so as to ensure that the push block 111 presses the terminal 100 to be welded and the push plate 121 clamps the terminal 100 to be welded.

[0071] In some embodiments, if the push plate 121 and push block 111 have no limit on their sides during movement, they will tilt and move under the action of the first inclined groove 1181 and the second inclined groove 1271. Therefore, as follows: Figure 14 As shown, the limiting body 13 has a first groove 134 and a second groove 135 on its side facing the push plate 121. The bottom of the first groove 134 has a first limiting groove 131, and the bottom of the second groove 135 has a second limiting groove 132. The extending directions of the first limiting groove 131 and the second limiting groove 132 are the same as the width direction of the limiting body 13. The push block 111 is disposed in the first groove 134 and is in contact with the side wall of the first groove 134. In this way, the side wall of the first groove 134 is a limiting side wall relative to the push block 111, preventing the push block 111 from moving along the length direction of the limiting body 13. The push plate 121 is disposed in the second groove 135 and is in contact with the side wall of the second groove 135. In this way, the side wall of the second groove 135 is a limiting side wall relative to the push block 111, preventing the push plate 121 from moving along the length direction of the limiting body 13.

[0072] The pusher block 111 includes a pressure plate and a first guide block. The width of the pressure plate is smaller than the width of the first guide block, and the pressure plate protrudes along the length of the first guide block. The first guide block is disposed in the first groove 134, and the thickness, length, and width of the first guide block are the same as the height, length, and width of the first groove 134, respectively. In this way, the first guide block can be limited by the first groove 134. The pressure plate is fixedly connected to the first guide block, and the first guide block provides guidance for the pressure plate, so that the pressure plate can move smoothly within the first groove 134.

[0073] The push plate 121 includes a clamping plate and a second guide block. The width of the clamping plate is greater than the width of the second guide block, and the clamping plate protrudes along the length of the second guide block. The second guide block is disposed in the second groove 135, and the thickness, length, and width of the second guide block are the same as the height, length, and width of the second groove 135, respectively. In this way, the second guide block can be limited by the second groove 135. The clamping plate and the second guide block are fixedly connected, and the second guide block provides guidance for the clamping plate, so that the clamping plate can move smoothly.

[0074] Since the width of the pressure plate is smaller than the width of the first guide block and the width of the clamping plate is larger than the width of the second guide block, instability may occur when the push plate 121 and the push block 111 move. Therefore, in some embodiments, the limiting body 13 is also provided with a plurality of cover plates 19. The cover plates 19 are respectively provided on both sides of the clamping plate and the pressure plate, and a gap is formed between the cover plates 19 that allows the clamping plate and the pressure plate to pass through, thereby providing guidance for the clamping plate and the pressure plate.

[0075] In some embodiments, as Figure 15As shown, the lifting mechanism 2 includes a third driving member 24, a base plate 26, pressure blocks 27, and a slider 28. The base plate 26 is provided with a receiving groove 261. Specifically, the base plate 26 has a C-shaped structure. Only the specific structure of the base plate 26 is provided here. As long as the position of the pressure block 27 and the slider 28 can be limited, it is within the protection range. The C-shaped structure of the base plate 26 allows the base plate 26 to form a receiving groove 261. The pressure block 27 and the slider 28 are both set in the receiving groove 261. The pressure block 27 is set at both ends of the slider 28 and is fixedly connected to the base plate 26. The slider 28 is connected to the third driving member 24 and can slide relative to the pressure block 27. A pressing mechanism 1 is provided at the top of the slider 28. Different pressing mechanisms 1 achieve the purpose of lifting and lowering under the drive of different sliders 28, thereby meeting the pressing needs of the irregular terminal 100. The base plate 26 and the pressure blocks 27 on both sides restrict the left, right, front and back directions of the slider 28.

[0076] Specifically, the pressure block 27 has a first sliding inclined surface on the side facing the slider 28, and the slider 28 has a second sliding inclined surface on the side facing the pressure block 27. The first sliding inclined surface and the second sliding inclined surface are in contact. In this way, the slider 28 moves up and down under the guidance of the first sliding inclined surface of the pressure block 27, so as to prevent the slider 28 and the pressure block 27 from separating.

[0077] In some embodiments, the lifting mechanism 2 further includes a baffle 29, which is connected to the base plate 26 to form a receiving cavity, where the slider 28 and the pressure block 27 are both located. The baffle 29 prevents the base plate 26 from deforming under gravity, thereby improving the strength of the base plate 26.

[0078] In some embodiments, there are two upgrading mechanisms 2. Since there are two lifting mechanisms 2, there are also two base plates 26. A support plate is provided between the two base plates 26. The support plate is used to fix the support platform 3 of the support terminal 100. The support plate is fixed relative to the base plate 26, so that the slider 28 and the limiting body 13 can be raised and lowered relative to the base plate 26.

[0079] The lifting mechanism 2 also includes a limiting member for limiting the downward and falling distance of the third drive member 24, for example, such as Figure 11 As shown, the limiting component is the second limiting bolt 42. One end of the second limiting bolt 42 passes through the limiting body 13 and is fixed relative to the limiting body 13. Specifically, the second limiting bolt 42 is threadedly connected to the limiting body 13. The length of the end of the second limiting bolt 42 passing through the limiting body 13 is adjustable, and one end of the second limiting bolt 42 is set opposite to the base plate 26. When the second limiting bolt 42 descends with the limiting body 13, the second limiting bolt 42 is limited by the base plate 26. Therefore, the limiting body 13 cannot continue to descend with the slider 28 under the action of the second limiting bolt 42. The second limiting bolt 42 is used to adjust the position of the pressing mechanism 1 to accommodate terminals 100 of different thicknesses.
